Fortunately, no one got seriously injured in the process. "I did all of my stunts and a stunt double did them, too," Gillan said. "I refused knee pads at one point and of course then I bruised my knee but that was it."

Gillan not only shaved off her gorgeous ginger locks for the Guardians role, but the Scottish beauty endured sitting in a makeup chair for five hours every day while a team applied prosthetics and turned her skin an eerie blue. "It was amazing," Gillan said of the first time she looked in a mirror as Nebula. "It was creepy and weirdly doll-like, child-like almost."

In Oculus, Gillan plays a young woman who returns to her childhood home in seatrch of the demons living in an antique mirror that turned her parents into deadly zombie-like creatures. She brings along her brother (the super-hot Brandon Thwaites), who's just been released from a mental institution.

And get this—it's Gillan's own mother who is especially proud of her daughter's work in the blood-filled gorefest. "I could do multiple amazing films but she would never be as excited as this one," she said. "It's a horror film and it's creepy. She's really into that kind of stuff."
